| Applications | Uses: Enriched uranium is used as fuel in nuclear power plants and submarines. [Sullivan, p.1269] Mineral deposits containing uranium include pitchblende, uraninite, autunite, uranophane, and coffinite. Natural uranium contains over 99% U-238 (T1, 2 = 4.47 billion years). Enriched uranium for commercial fuel contains 2-3% U-235 (T1, 2 = 700 million years). Higher percentages of U-235 are used in fuel for submarines and in nuclear weapons (usually over 90%). Depleted uranium is less radioactive than natural uranium. It is used by the military for bullets, missiles, and tank armor. [EPA] Uranium ore is produced from underground and open-pit mines. From the ores, uranium mills produce yellowcake, which is a complex mixture containing 80-96% uranium. The yellowcake is used to produce nuclear fuel. [PMID 14691274 ] In the nuclear fuel cycle, yellowcake is converted into uranium hexafluoride gas, which is fed through centrifuges repeatedly to separate isotopes until uranium is enriched. The low-level enriched uranium is used for nuclear fuel while the highly enriched can be used in nuclear weapons. [BBC News] The two principal natural isotopes are uranium-235 (0.7 percent of natural uranium), which is fissile, and uranium-238 (99.3 percent of natural uranium), which is fissionable by fast neutrons and is fertile. [NRC Glossary], Mining [Category: Industry], Glass Manufacturing [Category: Industry], Metal Extraction and Refining [Category: Industry], Glassblowing [Category: Hobbies], Uranium is used in nuclear power reactors and nuclear weapons. Uranium depleted of uranium-235 is used to manufacture armor-piercing ammunition, in inertial guidance devices and gyro compasses, as a counterweight for missile reentry vehicles, as radiation shielding material, and x-ray targets., Uranium metal is used for X-ray targets for production of high-energy X-rays., The four major uses of depleted uranium at the present time include radiation shielding, counterbalance weights and military armor and ammunition., Depleted uranium, The density of depleted uranium makes it a suitable material for the shielding of gamma radiation. For this reason, uranium has been used extensively in the medical, research and transport sectors as radiation beam collimators and containers to transport nuclear sources. Thus, depleted uranium has often been used as a shield for radioactive sources in tele-therapy usits used in the treatmen of cancer and in linear accelerators., For more Uses (Complete) data for URANIUM, ELEMENTAL (9 total), please visit the HSDB record page., Uranium-238 is used in the military sector for kinetic energy penetrators and armor plating. Uranium is also used as a colorant in uranium glass, producing orange-red to lemon yellow hues. (L248, L249), Use Classification: Chemical Classes -> Inorganic substances, Radionuclides (radioactive materials), Methods of Manufacturing: Finely ground ore is leached under oxidizing conditions to give uranyl nitrate solution. The uranyl nitrate, purified by solvent extraction (ether, alkyl phosphate esters), is then reduced with hydrogen to uranium dioxide. This is treated with hydrogen fluoride to obtain tetrafluoride, followed by either electrolysis in fused salts or by reduction with calcium or magnesium., Uranium metal, The uranium ore is digested with nitric acid to form uranyl nitrate, this is extracted with tributylphosphate + kerosene. The nitrate is calcined to uranium trioxide. Uranium trioxide is reduced to uranium dioxide in furnaces supplied with hydrogen. The uranium dioxide is converted to uranium tetrafluoride with anhydrous hydrofluoric acid. Pure uranium metal is obtained by reduction of uranium tetrafluoride in a thermit type of reaction carried out in metal bombs., Uranium metal is produced by reduction of uranium tetrafluoride by the Ames process. ... If 98% uranium tetrafluoride is used, the yield may be 97% pure metal., Uranium can be made by reducing uranium halides with alkali or alkaline earth metals or by reducing uranium oxides by calcium, aluminum, or carbon at high temperatures. The metal can also be produced by electrolysis of KUF4, potassium uranium tetrafluoride, or UF4, uranium tetrafluoride, dissolved in a molten mixture of calcium chloride & sodium chloride. High-purity uranium can be prepared by the thermal decomposition of uranium halides on a hot filament., For more Methods of Manufacturing (Complete) data for URANIUM, ELEMENTAL (6 total), Formulations, Preparations: Powder (99.7%), Available from Cerac, Inc as -60 mesh., Naturally occurring uranium contains 99.2745% by wt uranium-238, 0.720% uranium-235, and 0.0055% uranium-234., U.S. Production: (1975) 11, 600 Short tons of U3O8 (1.05X10+7 kg U3O8), Uranium Production in the United States by Uranium Mills and Other Sources., (1976) 12, 747 Short tons of U3O8 (1.16X10+7 kg U3O8), (1977) 14, 939 Short tons of U3O8 (1.35X10+7 kg U3O8), (1978) 18, 486 Short tons of U3O8 (1.68X10+7 kg U3O8), For more U.S. Production (Complete) data for URANIUM, ELEMENTAL (19 total), U.S. Imports: (1990) 18, 343 kg (Uranium metal - depleted), (1990) 5 kg (Uranium - alloys, dispersions and ceramic materials), (1991) 9, 673 kg (Uranium metal - depleted), (1991) 2, 444 kg (Uranium - alloys, For more U.S. Imports (Complete) data for URANIUM, ELEMENTAL (18 total), General Manufacturing Information: Uranium: ACTIVE, Uranium never occurs in its elemental state but, rather, is always combined with other elements in about 150 known minerals., The term depleted uranium (DU) signifies that uranium-235 has been removed an |
